Official summary
Some 2020-2021 Expedition vehicles may exhibit an intermittent no auto restart during auto-start-stop operation with a Shift To Park Restart Engine message displayed in the message center. Follow normal Workshop Manual (WSM), Section 303-14 diagnostics if this concern occurs. If diagnostics are inconclusive inform the customer that Ford is currently investigating this concern and that they can continue to drive the vehicle with the auto stop/start system turned off. Monitor OASIS for further updates.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
